6) This is the key Section. Write in here:
In (fill in date) , we took out a fixed rate mortgage which entitled us to a tracker rate at the then prevailing tracker rate at the end of the fixed rate period
In (fill in date), this fixed rate period expired and we were not offered the prevailing rate
AIB is claiming that the prevailing rate would have been around 7.9%
We argue that AIB did have a prevailing tracker rate and it was ECB +1.25%
We want the tracker rate of ECB +1.25% from the date our fixed rate ended.
We want a refund of the overpayments made since then.
We want compensation of 15% of the overcharge.
We want a return to the tracker rate from now until the end of the mortgage.
Other than the 15%, we are not seeking any further compensation or professional fees.
The full argument is set out in the attached.
